The seat

 

 

I was originally going to make the seat by first making a foam version then using that to make one in fibreglass, however I discovered that the cost of the fibreglass was more than buying a seat. Then I found this one on Finn and I decided that it is not only much better than anything I could make but cheaper too. I me took some measurement of the frame and drew it to scale using GeoGebra. I then imported it to Algodoo where I compared the frame to the drawing of the seat.

The red lines are the existing frame and the blue ones where it should be to accept the seat. I think that all I need to do is cut and bend. I also superimposed the seat onto the bike frame.

I think the dimensions are pretty perfect. The only tricky opasrt will be to weld some new support struts sine I will have to cut away the strut that goes from the body of the frame to the end of the seat.

Why won't axle rod go through wheel?

 The say that if you put questions in your website text then it is more likely to be found by search engine. Hence the title to this post. This is whet I searched for but although I found many people with the same problem I found no answer. I used about 8 hours trying but the rod just wouldn't go through. I used a slightly smaller rod as a guide but still no joy. Eventually I realised that the rod would not pass through the small spacer. Eureka, I had swapped the spacer with the washer. The rod passes through the space but only the threaded part goes through the washer. Satisfied at slving the problem but frustrated that it took so long. I don't want to look at that axle so I'm posting a photo of the bike with newly painted tank. Nowhere near this stage yet but I like looking at it.

 I am waiting for parts so that I can finish the bike. It won't be road legal but it should run and should look a lot faster than it is. The actual bits I am missing are the instruments and head light.. Once that end is done, I can get on with the rear end and sort out the exhaust. My current thought is to buy a simple silencer and some curved pipes from Biltema and put together my own exhaust, there aren't so many curves. I am going to take measurements from the photo using the programme GeoGebra.

 I needed to make some sort of panel to cover the electrics under the seat and I thought I would use the steel plate a the back of our old kitchen stove. I had forgotten just how difficult it is to cut with the shears but I managed some rough shapes and folded the edges over to get rid of any sharp edges. The results are quite horrible but will have to do for now.
